Use of application in Real life:

Weather radars play a vital role in short-term weather forecasting and for meteorological research. They are being used routinely in meteorology to monitor storms and follow their evolution, as well as observe winds and detect regions where severe weather might develop. Some of the important uses are:

1. Short-term public weather forecasts: One of the primary applications of radar data is short-term (0-4 hr) weather forecasting, also known as “now-casting”. It proves extremely useful to issue warnings when severe weather develops rapidly in the vicinity.

2. Short-term forecasts for aviation: Another application of radar is to improve short-term weather forecasts around airports, also known as "terminal forecasts". Aircrafts are very susceptible to severe weather. Icing, hail, very heavy rains, rapid wind shifts and downbursts creates difficult situations for aircrafts. All these meteorological conditions can be detected at least to some extent by weather radars and therefore radar has an important role to help aircrafts steer out of dangerous areas.

3. Radar can be used to find rain - no rain areas using cloud imagery. The rainfall amount can also be approximated.

4. River and sewer flow forecasting: Rivers take their water from rain. Radar measures rainfall and snowfall rates over large areas, and can also be used to make short-term predictions of precipitation amounts. Therefore, radar can be used, in conjunction with appropriate models of river flow, to predict the flow and the level of the water in a river. Sewers can be viewed as a special kind of river. They cover small areas, but in many ways they can be viewed as rivers. If sewers are predicted to overflow, special measures (like diverting water from one part of the network to the next) can be taken to prevent damage to property.

5. Wind velocity: This is done by using Doppler radar which measures the radial velocity, which is the component of the wind going in the direction of the radar (either towards or away). There are many other practical applications of radar data in meteorology like it can be used to determine the refractive index, measurements of moisture, modeling of mold on crops, etc.
